AUTOMATIC SWITCH.

App li eation filed November s, 19:22.

To all whomdt may concern. a Be it known thatv we, JAMES E. SLUssnR andSAMUEL A. S'rovnn, citizens of the United States, residing atMarsteller, in the county of .C'ambria' and State of Pennsylvania, havinvented certain new and useful Improvements in Automatic Switches, ofwhich the following is a specification.

This invention relates to automatic switches primarily adapted forapplication a to the track-ways employed: in mines or stone quarries,whereby the dump cars run- 1- ning over the track ways will control theactrack-way.

tuation of-the switch for'allowing the cars to run alternatelyupontheinain and side In m nes or provided a main and side track-way eachprovided with a cartipple or storage bin either upon' orbeneath thetrack-way and heretofore, ithas been necessary *to run a (-aruponthemain track-way and then throw a switch for allowing the next cartopass over theside track-way whereby they may be dumped. This procedureoccasions a great amount of trouble and necessitates the employment of aswitchman for throwing the switch, for controlling the movement of I thecars, alternatelyuponeach track-way.

It is therefore the primary object of our invention to provide a switchwhich at all times will be controlled by the movement of thecars overthe main and side track-ways for permitting these cars toalternatelypass over the said main and side track-ways.

The nature and advantages of the invenbetter understood when thefollowing detailed description is read in connection with theaccompanying drawings, the invention residing in the construction,combinatiomand arrangement of parts as claimed.

In the drawings forming plication, like numerals cate similar parts inthe wherein 2- F igure 1 is a plan view of my improved switc the pointsthereof being thrown so as to allow the oncoming car to pass onto theside track-way. A i

Figure 2 is a view similarto Figure 1, but showm the switch points ashaving been controlid by a car passing over the side of referenceindiseveral views, and

' track-way for positioning these points so as quarries there isgenerally ends of the switch I adjusted with respect to the ad acentrails part of this ap- Serial No. 599,637. r

Figure 8-is enlarged plan view ofthe front ends of the switch points,and the con- TENT orr oEuip arm positioned Figure 6 is a fragmentarylongitudinal sectional view upon the line 6-6 of F igure 1. i i a v i vFigure 7 1s a transverse crosssectional view upon the line/7+7 ofiFlgure .1, and

Figure 8 is a detail perspective'view of one of the car actuated armsfor-the switch points. I

With reference to the drawings, and in particular to Figures land 2, wehave shown our improved switch as being providedbetween a main andjsidetrack-wayA and B respectively. In practicing our invention we havevprovided a, conventional type of ends a rod 9, the inner end of which isyoked as at 10 forreceiving therebetween a desirable form of turnbuckle11, whereby these points may be properly As morec learly shownin v ofthe track sections. The outer ends of each of the rods 9 are similarlyyoked as at 12 for pivotally receiving thereon one arm of a bell crank13, which bell cranks are pivotally secured as atlt to one of the adjacent ties at. i a

The other arm of each'of the bell cranks 13 are pivotally secured, to alink 15 carried by a chain 16, one of which extends parallel with theouter rail of the main track section, and the other of which extendsparallel to the outer rail of the side track seotlon as more clearlyshown in Figures 1,2 and At a point spaced from the switch points 6 and7 for a distance greater than'the length ofthe dump cars passingover thetrack sections, the outer rails a" and 6' of the main and I havepivotally secured adjacent thereto an arm member 17 to be actuatedby thewheels of the cars passing thereover as more clearly side track-waysrespectively,

The arms 1? ad and rigidly secured tothe opposite end of this shaft 19 a vertically extending arm or plate21. It isto beunderstoodfurther, thatthe base and tread portions of eachof the ra ls a and Z are suitably channeled and vice versa.

as shown io'r'allowing a free swlngingmovcmen? of the members 17. Thebefore mentioned chain sections '16 are'eaoh connected through themedium of a link 22 with its respective arm 21, adjacent the outer railsof each tracksection as noreclearly shown in Figure 5, and in view ofthe above description, it will. be readily understood that with theswitchpoints 6 and 7 in a position as shown in Figure .1, an oncomingcar w ll be switched to the side track-way B, at which time, the wheelsthereof will engage he headed'end 18 of the operating member 17; forthrowing the switch points 6 and 7 into the position shownjin-Figure 2for allowing the next car to run upon the main track section A It is tobe understood that should it be desirable at any time to use only onetrack section, the device may be disconnected in several different ways,such and a description or npresent invention, it is nevertheless to befor instance, as disconnecting the bell cranks 13 from the switch pointcarrying rods 9 and it found desirable, turn buckles 16 may 1. Inautomatic switches, a rocking arm pivotally supported adjacent one ofthe rails oi -the main and: side track-way,,the upper end 0-? theserocking arms adapted to extend above the tread of their adjacent railsto be actuated by the wheels of a car passing thereover, and connectingmeans between each rocking arm and theswitch points of the vswitch forcontrolling the -movement thereof;

v 2. ln an automatic switch, a 'rocning arm pivotally supported adjacentof the main and side section, the upperend of which normally extendsabove the said rail'to be actuated by the wheels of a car passingthereover, rigid connections between the switch points of the switch andchain connections between the switch point-connections and the saidrocking arms whereby the movement of the switch points are controlled'bya car engaging the rocking arm upon either themain or side track-way.

In testimony whereof we aflix our signae tures.
